The tracer tool and the operating tool are mounted. in. sutabieldeeices,these devices being interchangeable, that is, either of the todlscan'be'plfed on the lrrh that projects most or the one that projects least fromf the head or support. In the form Ishown the tracer tool 46 is shown inthe outermost position, being mounted so that it is verticallyadjustable in a device 4:7, being` held in position by a setscrevv 48passingthough the body portion ofthe device it?` thetoolholder or device47 bein slidabl by teastntta dote-'tailed Slidey eending'n they groove50 of the end 3,9, 'and being"A held in its various horizontallyadjusted positions by; a" lsuitabie'ysetjsere t 51, and the operating'tool is mountedlin a device or holder 52 which has an extension 53 thattits in a `dove-tailed groove 54 in vthe end 38 and is `held in adjustedposition by a set scelw 55. `A spindle 56 is adapted to carry thenperatingtool 57 in a suitable chuck or by any other means, and isprovided at its upper end with means for attachin it to a flexible shaft58 and is also prefera ly Vprovided with a momentum head 59 that insuresits steadyo eration.y

It Will be evident that if the handle 32 is turned and the arms 22 and23 are not locked against movement, these arms Will be slid so as toproject more or less from the head, and if the pinions operating thesearms are of different sizes, their ratio will determine the ratio ofmovement of these arms.

If the machine is to be used manually, one of the handles is swung outto the dotted position shown in Fig. 2, and the device is grasped muchin the same way as a carpenter Would grasp a jack plane, the handlebeing grasped by the right hand, the tool end of the device being guidedby the left hand, and by a back and forth movement or swinging movement,as desired, the tracer tool and the operating tool can be made to movein any desired direction, the ratio of their movement being defined bythe ratio of the pinions 27 and 28 one to the other.

If a reproduction is to be made smaller than the pattern, the operatingtool is put at the innermost position and the tracer tool at theoutermost position, and if a reproduction is to be larger than thepattern, the tracer tool is put at the innermost position and theoperating tool at the outermost position.

Another Way of using the device is to fasten the pattern and the wor kin position and then operate the device from the tracer tool, guiding itin the desired direction, or in case a pattern of Well defined outlineis to be followed, simply placing this tracer tool on the pattern.

In Fig. 5 I illustrate a pattern 74, the tracer tool 46 being shown invarious positions therein, and corresponding positions of the operatingtool 5T are shown on the smaller reproduction made thereby. Assumingthat this is a groove that is to be routed in a piece of material, thetracer tool., following the groove in the pattern, causes acorresponding but smaller reproduction by the operating tool. The upwardmovement of the tracer tool causes a corresponding upward movement ofthe operation tool by reason of the strip 69 being raised when the toolholder 4T is raised, the strip 69 in turn raising the tool holder 52,these parts returning by gravity to their positions, this gravitationbeing assisted usually by the fact that the strip 69 is made of yieldingor spring material. When it is desired to make straight parallelreproductions, the rotatable head can be placed in the proper position,locked by the latch 17, and then straight sliding movement of the arms22 and 23 results in similar movement by the tracer tool and theoperating tool.

In Fig. 6 I illustrate a means for regulating or controlling the feedingof the arms when such Feeding should be very gradual, such, forinstance. as when a very fine tool is traversing a tine piece of Work,on each traverse the tool is advanced but a very slight distance. Onemeans of controlling this is illustrated in Fig. 6, in which the bracket76 is mounted on a swinging element, such as the plate 7T, which ispivoted at T8 and the device can thus be swung into and out of operativeposition. The bracket conA tains a shaft 76a which has on the topthereof a hand piece 79 by means of which it can be turned, the handpiece being adapted to be held against accidental movement by suitablemeans, such as the strip #52, which has a slight projection, and thestrip 82 being made of spring material, it snaps into the serrations orgrooves in the edge of the hand piece 79 and holds the hand pieceagainst: accidental movement. lV hen, however, the tool is to beadvanced, the hand piece T9 is turned and the worm 8l on the shaft T6 engages the worm gear Si), which is provided on the edge of the wheel 32,and a vvery slight advance of the bar carrying the tool is thus providedfor.

Other means of insuring such gradual advancement can be provided, solong as it makes it unnecessary for the operator to attend to thetedious slight advance `for each time the tool traverses the Worklaterally.
